Abstract: A wind turbine comprises wind turbine blades extending substantially radially from a hub on a main shaft having a substantially horizontal axis. The blades together with the hub form a rotor, which can be put into rotation by wind. The main shaft is rotatable mounted in a nacelle on top of a tower, and the nacelle may be rotated around a vertical axis in relation to the tower to adjust the rotor in relation to a prevailing wind direction. The wind turbine further comprises a yaw brake comprising a brake calliper and a brake disc or ring having a first side with a first surface and second side with a second surface, the yaw brake, when activated, acting as a rotation restriction of the nacelle in relation to the tower. The brake disc or ring is provided with one or more grooves formed in the first and/or second surfaces.

Abstract: A touchpad- or touch screen-based device has a touch-sensitive sensor surface and can generate electrical and/or optical signals dependent on the placement and/or movement of a finger physically contacting the sensor surface. The sensor surface comprises a corrugated surface in at least one sub-area, thereby providing a user with two modes for finger movement across the sensor surface, namely a first mode for sliding movement at a first finger pressure, and a second mode for guided movement at a second finger pressure higher than the first finger pressure.

Abstract: The invention relates to a method for enabling scrolling on a display in a first direction by turning a scroll wheel of a computer mouse without the need to lift a finger from the scroll wheel during scrolling. This is obtained by switching the mode of operation of the scroll wheel from a first mode of operation, mode 1, to a second mode of operation, mode 2, by performing an action, such as holding down a specific key. The program procedure for mode 2 is such that when the scroll wheel is first turned upon switching to mode 2, a first direction of turning is de-fined. Continued turning of the scroll wheel in either the first direction of turning or another direction of turning will cause a scrolling on the display in the first direction.
